RSS import

Users with internet access should be able to import RSS feeds (via Tor) and re-publish them as Briar blogs.

First iteration:

UI for importing a feed -- no preview, show an error if the feed can't be fetched and parsed (#483 (closed))
Fetch the feed periodically in the background -- not via Tor (#484 (closed))
Extract new entries from the feed -- not fetching the full text (#485 (closed))
Convert any new entries to Briar blog posts -- just strip HTML tags (#486 (closed))
Post converted entries to the user's personal blog (part of #486 (closed))
Simple UI for Managing RSS Feeds (#483 (closed) & #517 (closed))

RSS/Atom Java libraries

actively maintained and looks to be the most popular on the net
Does not support Android fully, support will come with ~~2.0.0~~ 1.6.1 version
quite big with lots of stuff we don't need such as feed generation, but looks like these are in separate jars
Has a ROME Fetcher to fetch the feeds, but is deprecated in favor of dedicated HTTP libraries such as Apache HttpClient. We can use a library as okhttp as well and just pass the InputStream to the feed parser.
